A Yukon spool like the one Trail-Gear installed for us delivers 100-percent traction to both tires all the time and should therefore never be used on pavement. The benefit of this arrangement, aside from low cost, is its simplicity. With a full spool there are no gears, clutches, or moving parts to worry about.
